2. 2 Pipe Flow Experiment: Head Loss and Friction Factor in Pipe Flow  Why do we need a pump to pump fluid from place to place?  What does a pump do anyway?  How much is energy loss in a piping system?  What size/power of the pump is needed? http://commons.wikimedia.org/wiki/Image:Piping_system _on_a_chemical_tanker.jpg http://connection.lww.com/Products/sadler/images/figurelarge11-46.jpg

11. 11  What is energy or head loss?  How do we quantify it?  How do we measure it? How can we determine it from an experiment?  How much is “energy loss” in pipe flow?  If I increase the volume flowrate twice, how much is the energy loss increased?  What is the required power input at the pump (heart, etc.)?
